Fenn Trap Advice
For Fenn Traps to be effective, they must be positioned so that the target animal passes between the jaws of the trap and not over the ends of the jaws. Also, Fenn Traps have a tendency to push animals upwards when triggered.
To improve their efficacy and prevent injury to non-target animals, it is a legal requirement within the UK that set Fenn Traps must be placed inside a suitable natural or man-made tunnel. Alternatively, an appropriate purpose-made container may be used.
The Elgeeco Fenn Cage (advertised above) is suitable for Mk 4 Fenn Traps only.
Mk 6 Fenn Spring Traps require a larger tunnel or container made of a suitable material such as wood or wire mesh.
